I was against trying it at first as I am so anti drug
Alcohol is a drug, kills thousands each year.
Cigarettes, worse still.
Pain killers (opiates) prescribed by doctors are of the amphetamine group - speed. Which is believe it or not what they used to prescribe even to kids?
Cannabis doesn't kill anyone.
Above all physically addictive, Cannabis is not. No withdrawal.
Nor does it make people violent or shoot each other. It doesn't generate any tax and the pharmaceuticals don't like you growing your own medicine, so what you are told or have been told in the past, is purely to put you off - the fact is compared to most other meds it is way better as is natural, not a compound of synthesized crap, with hidden side effects.
I have a severe medical condition which can give me violent stomach pain, which I liken to being randomly stabbed when you least expect it. Meds given to me by doctors have nasty side effects, nausea amongst other things - when it hits, I feel rough very quickly.
I discovered one or two lugs on a vaporizer with the demon cannabis (no tobacco or combustion), within 2 minutes made my cramps & nausea disappear. Suprised at how quickly and how well it worked. No side effects.
I've known people with back issues & other muscle related disorders which also use with positive effects. I even told the specialist/doctor in Spain I was using a part of my own 'holistic' therapy - I wanted to make sure didn't have any adverse effects mixing with other drugs - he said is fine.
I would say to anyone contemplating - forget the nonsense you've been told over the years, the healing properties of Cannabis have been known for 1000's of years & it's only politics and greed which have hindered the use of this, by making people class Cannabis as a bad thing, but it's ok to drink booze, which is 1000 times worse, but that's legal, so it's not perceived as a drug, but it is and so much worse for you than the demonised weed.
Spain is more tolerant than the UK anyway & you can grow your own medicine here should you so wish, just don't be selling any - personal consumption only. You can take your plant and make your own, much stronger oil. On the internet, Rick Simpsons cure for Cancer (and other serious medical disorders). The CBD oil you can buy does offer lots of benefits, though really does depend on the strength and type of problem you are trying to treat.
Part of the issue is also the reason why we have CBD oil and not CBD+THC oil, is that to purchase the THC (the element that gets you high) is still illegal to sell, so they separate it out. The THC also is a contributing factor in the overall healing - but aside from legality buying (not legal, but you can grow own plant) - it does have the affect of making you high, which for treating someone medically, have to watch your dose carefully, as unlike CBD on it's own - THC will affect your state of mind, which you need to be cautious with as can't walk around all day stoned - well most of us who live in the real world can't.
